FM2540TS
product description
FM25XX is a low-power primary-side feedback (PSR) switching power supply chip with integrated high-power MOSFET, suitable for isolated high-efficiency low-power portable device charger applications. FM25XX adopts the unique primary-side feedback control technology with constant current and constant voltage function, and the unique PFM+PWM technology to reduce the power consumption of the chip under light load to achieve high-efficiency applications. FM25XX has output line loss compensation technology to ensure sufficient output power under high current. In addition, FM25XX also integrates over-temperature protection, VCC under-voltage protection, VCC over-voltage protection, output short-circuit protection and other technologies. FM25XX adopts compact DIP/SOP package, which is convenient for system design and wiring.
